Hash JoinhjoinAlso used for inner joins and left and right outer joins and typically faster than a nested loop join. Hash Join reads the outer table, hashes the joining column, and finds matches in the inner hash table. Step can spill to disk. (Inner input of hjoin is hash step which...

一. NESTED LOOP: 对于被连接的数据子集较小的情况,嵌套循环连接是个较好的选择。在嵌套循环中,内表被外表驱动,外表返回的每一行都要在内表中检索找到与它匹配的行,因此整个查询返回的结果集不能太大(大于1 万不适合),要把返回子集较小表的作为外表(CBO 默认外表是驱动表),而且在内表的连接字段上一定要有索...
